Abstract: 864,579. Photographic cameras. GAUTHIER G.m.b.H., A. March 31, 1959 [Sept. 2, 1958], No. 10771/59. Class 98(1) A photographic.camera has a device for automatically indicating depth of field for any lens aperture and focus setting, in which two rings coaxial with a rotatable focus scale and each bearing a pointer for indicating limits of depth of field on the focus scale are adapted to be rotated in opposite directions by a system of gearing actuated by a toothed segment eccentrically mounted with respect to the axis of rotation of the two rings and the focus scale, which axis is parallel to the optical axis, so that the segment and rings have parallel planes of motion, such segment being actuated by a cam disc moved by mechanism controlling the lens aperture. In the exploded perspective view shown pointers 11a and 12a indicate the limits of the range of focus on distance scale 5 of a rotatable focussing ring, and are adjusted in position according to the setting of diaphragm setting ring 7. On rotation of ring 7, cam disc 18 is caused to rotate, by engagement of arm 19 with fork 18b in arm 18a, and ring 14 is rotated about pivot 14b by the co-operation of either two pins 20, 21 or alternatively two lugs (not shown) with cam surfaces 18d and 18c. Rotation of ring 14 is transmitted to rings 11 and 12, so as to rotate them in opposite directions, by means of tooth segments 14a, 11b, and 12b and transmission gears 15, 16, and 17 mounted on shaft or bush 22. The diaphragm and shutter speed setting rings are coupled in known manner for adjustment in terms of light values. In a modification, the two pins or lugs (20, 21) and the two cam surfaces 18d and 18c may be replaced by a cam slot or groove and a single cam follower element on the toothed segment 14.

Abstract: 678,801. Sifting-apparatus. ROSS, W. May 8, 1951, No. 10809/51. Class 117 In a screening apparatus of the kind comprising rollers e, a over which the material to be screened passes in a direction transverse to the rollers, the roller a is pivotally supported by bolts c on a shaft b and is adjustable relatively to the roller e by a handwheel h and screw f. A spring is also incorporated in the handwheel mechanism to allow vibratory movement of the roller e. The chain drive v for the rollers includes a fixed sprocket q and a resiliently mounted sprocket q<1>, the latter preventing overstrain of the chain when the position of the roller a is adjusted. The arrangement is such that large pieces of material can be dealt with, without damage to the mechanism, a piece likely to cause a jam between the rollers producing an upward jump of roller a to allow the piece to fall between the rollers, or, if too large, to carry it over the surface of roller a to the " oversize " delivery shoot.

Abstract: 1.25,448. Ricardo, H. R. Aug. 2, 1916. Four-stroke-cycle engines; charge, cooling.- In Diesel and other engines which work with super compression and ignite their charges wholly or in part by the heat of compression, cooled combustion gases are admitted to the cylinder after the opening of the exhaust valve to reduce the temperature of the parts subject to the burning gases, and the extra charges are heated before admission. The invention is shown in the Figure applied to an engine compressing air for scavenging &c. in the lower end of its cylinder. At the end of the suction stroke, air compressed in the pump space F traverses a cooler H<2> for the burnt gases and is heated therein by contact with a passage J before it enters the cylinder through terminal ports B. At the end of the working stroke, burnt gases enter the cooler and, after having their temperature reduced, re-enter the cylinder through the ports B to be finally expelled through an exhaust valve. A restricted passage may be provided at one or both ends of the cooler.

Abstract: 421,101. Oil engines. SAURER, H., Arbon, Switzerland. April 12, 1934, No. 11043. Convention date, Feb. 19. [Class 7 (iii)] In an oil engine having a combustion chamber separated from the cylinder by a throttled opening, air is admitted to the cylinder tangentially, rotates about the cylinder axis, and is deflected by the curved walls of the combustion chamber, as it is forced through the throttled opening, so that it performs a whirling motion in the combustion chamber which proceeds helically and in a circle. As shown in Fig. 6, the air is admitted through the inlet valve 3 and is forced through a throttled opening 8 into the combustion chamber 7, which has either a plane end or a protuberance 11<1>, which, with a projection 10 which may be provided around the fuel nozzle 5, guides the air. In the two-stroke engine shown in Fig. 7, the air is admitted tangentially through ports 12, and a conical projection 14 on the piston 2 guides the whirling air in the combustion chamber 7, which is formed in the cylinder head.
